摘要
采用 Ritz 法分析局部载荷作用下横向加劲腹板的屈曲强度,板内应力采用有限条法计算,给出了加劲肋的临界刚度比及板的最大屈曲系数的计算图表.分析结果表明,当载荷相对尺寸小于0.5.板长宽比小于1.38时,横向加劲腹板比纵向加劲腹板具有较高的临界载荷.
Using the Ritz method,this paper analyzes the buckling strength of plate with transverse stiffener under partial load.The internal stresses are calculated with finite strip method.Calculating diagrams for the critical rigidity rate of stiffener and the maximum buckling coefficients of plate are obtained.The analyzing results show the critical load of transversal stiffening plate is higher than that of longitudinal stiffening plate when the dimension of relative to load is less than 0.5 and the aspect ratio of plate is less than 1.38.
